TESLA POWERWALL BATTERY SCHEDULING

This guide applies to:

• Tesla Powerwall
• Tesla Powerwall 2
• Tesla Powerwall+

Managed through the Tesla App (iOS or Android).

Ensure:

• Your system is online in the app
• You have owner-level access
• The battery shows available stored energy

Open the Tesla App

• Tap Energy
• Tap Customize
• Select Time-Based Control
• Choose Balanced or Advanced

Why Time-Based Control?

Time-Based Control allows the Tesla Powerwall to discharge during higher-value time periods.
If the system is set to Self-Powered, the battery will prioritise powering your home and may not discharge as strongly during the Battery Happy Hour window.

In Time-Based Control settings:

1. Navigate to Utility Rate Plan
2. Edit your time-of-use schedule

Set the Peak period to:

• Start: 17:30
• End: 19:30

Save the schedule.

This signals the Tesla Powerwall that electricity is most valuable during this window, encouraging the battery to discharge.

To ensure energy is available during Happy Hour:

• Go to Energy Settings
• Locate Backup Reserve
• Set reserve to around 10–20% (typical recommendation)

If Backup Reserve is set too high (for example 40–50%), the battery may stop discharging early and keep energy reserved for outages.

Even if your battery discharges, grid export may still be limited if:

• Export restrictions exist in your network connection agreement
• Your DNSP export limit is lower than the inverter output
• Your home is consuming most of the energy

Typical DNSP export limits are:

• 5 kW single phase
• 10–15 kW three phase

(These limits vary by region and network.)

Between 5:30pm–7:30pm:

Open the Tesla App and check the Energy Flow screen.

Look for:

• Battery showing discharging
• Power flowing from battery to grid
• Grid export visible in the energy flow diagram

If the battery is discharging but export appears low:

• Your home load may be absorbing the energy, or
• Your export limit may be restricting grid export
